Comm #4532	Echinochloa crus-galli Herbaceous Vegetation » more details accession code: VB.CC.29362.ECHINOCHLOACRUS	Carsey et al 2003b	1	Echinochloa crus-galli (barnyard grass) is a nonrhizomatous, warm-season annual grass of Eurasian origin that occurs throughout the continental United States and southern Canada. It is locally common in floodplains, riverbottoms and seasonally wet habitats, but is also found in drier areas, and is most often found on distrubed sites. It occurs in a variety of forest, grassland and wetland communities (USDA FEIS 2002), but is most likely to occur as a dominant in disturbed sites.
Comm #4533	NY Heritage: Rocky summit grassland » more details accession code: VB.CC.29009.NYHERITAGEROCKY	Ecological Communities of New York, 2nd Ed.	1	A grassland community that occurs on rocky summits and exposed rocky slopes of hills. Woody plants are sparse and may be scattered near the margin of the community. Small trees and shrubs at low percent cover include eastern red cedar (Juniperus virginiana), shagbark hickory (Carya ovata), and red oak (Quercus rubra). Characteristic and dominant grasses include little bluestem (Schizachyrium scoparium), tufted hairgrasss (Deschampsia flexuosa), poverty-grass (Danthonia spicata, D. compressa), and Indian grass (Sorghastrum nutans). Other grasses and sedges include Pennsylvania sedge (Carex pennsylvanica), big bluestem (Andropogon gerardii), sweet vernal grass (Anthoxanthum odoratum), and deer-tongue grass (Panicum clandestinum). Other herbs include ebony spleenwort (Asplenium platyneuron), dittany (Cunila origanoides), fragrant goldenrod (Solidago odora), bush-clover (Lespedeza violacea), Greene's rush (Juncus greenei), and whorled loosestrife (Lysimachia quadrifolia). Characteristic nonvascular species include lichens and mosses on scattered rock outcrops.

Comm #4534	Tamarix ramosissima Shrubland » more details accession code: VB.CC.29442.TAMARIXRAMOSISS	Carsey et al 2003b	1	This broadly defined association includes moderately dense to dense shrublands on banks of large streams in the western Great Plains interior and southwestern U.S. and norhtern Mexico (Von Loh 2002). Stands are dominated by species of Tamarix (salt cedar), and introduced small tree or shrub. Two species are known in Colorado, T. parviflora and T. ramosissima. T. parviflora is more common on the western slope, but not as abundant as T. ramosissima. Tamarix was introduced from the Mediterranian and has become naturalized in various habitats, including salt flats, springs, and along streams and rivers, where it replaces natie vegetation (Von Loh 2002). The understory may consist of sparse to dense growth of native or introduced shurbs or herbaceous plants. Tamarix is tolerant of environmental extemes, long-lived, and extremely difficult to eradicate.
Comm #4535	CEGL004180 » more details accession code: VB.cc.29760.CEGL004180	UNKNOWN	1	This association occurs on frequently and infrequently flooded terraces along creeks and streams in the Lampasas Cutplain region and likely other areas of the Edwards Plateau of central Texas. At Fort Hood, Prosopis glandulosa (honey mesquite) occurs as a dominant in some riparian and alluvial situations on older terraces that do not flood frequently, but are within the floodplain. This vegetation is often low-statured and could be considered a shrubland. Other small trees may include Ulmus crassifolia (cedar elm), Sideroxylon lanuginosum (gum bully), Sapindus saponaria (wingleaf soapberry), Maclura pomifera (osage orange), Celtis laevigata (sugarberry), and Carya illinoinensis (pecan). The canopy is open and herbaceous cover is often high, with Nassella leucotricha (Texas tussockgrass), Bromus japonicus (Japanese brome), and/or Elymus virginicus (Virginia wildrye) dominating. Forbs typical of disturbed grasslands in central Texas are also often present, including Croton monanthogynus (prairie tea), Ratibida columnifera (upright prairie coneflower), Ambrosia psilostachya (Cuman ragweed), Phyla nodiflora (turkey tangle fogfruit), and Ruellia nudiflora (violet wild petunia).

Comm #4536	Adenostoma fasciculatum Shrubland Alliance » more details accession code: VB.CC.19637.ADENOSTOMAFASCI	Western Ecology Working Group of...	1	This widespread chaparral alliance of dry slopes and ridges of interior California is found between 10 and 1800 m elevation. It can occur on all slopes and usually occurs on xeric sites. Stands of this alliance usually occur on shallow, mafic-derived soils. This sclerophyllous, broad-leaved evergreen shrubland is dominated by Adenostoma fasciculatum. Mature stands are densely interwoven thickets of Adenostoma fasciculatum, with other species contributing very little to overall cover. Emergent trees of Quercus wislizeni may be present. Shrubs may include Arctostaphylos glauca, Salvia mellifera, Heteromeles arbutifolia, Eriogonum fasciculatum, Artemisia californica, Toxicodendron diversilobum, Yucca whipplei, and various Ceanothus spp. There is very little understory or herbaceous litter. This alliance intergrades with other chaparral types, coastal scrubs, and grasslands.
